Multicenter StudyHemiarch versus Extended Arch Repair for Acute Type A Dissection: Results from a Multicenter National Registry.
We compared perioperative outcomes of patients with acute type A aortic dissection undergoing hemiarch (HA) versus extended arch (EA) repair with or without descending aortic intervention. ⋯ Extended arch interventions pose similar perioperative mortality and neurologic risks as Hemiarch. Descending aortic reinforcement may promote malperfusion restoration. Extended techniques should be approached with caution in acute dissection due to increased risk of adverse events.

Observational StudyOutcomes of emergency surgery for acute type A aortic dissection complicated by malperfusion syndrome.
The study objective was to determine the impact of malperfusion syndrome on in-hospital mortality and midterm survival after emergency aortic arch reconstruction for acute type A aortic dissection. ⋯ Malperfusion syndrome is associated with higher in-hospital mortality and reduced survival for patients with acute type A aortic dissection, with the risk of mortality increasing as the number of malperfused vascular beds increases. Coronary malperfusion syndrome and neuro-malperfusion syndrome may represent a high-risk subgroup of patients presenting with acute type A aortic dissection complicated by malperfusion syndrome. Finally, malperfusion syndrome may benefit from immediate surgical intervention to restore true lumen perfusion, as opposed to operative delay.

Encouraging Results of Blood Conservation in Neonatal Open-Heart Surgery.
To report early outcomes of blood conservation in neonatal open-heart surgery. ⋯ Bloodless surgery is possible in a significant proportion of neonates undergoing open-heart surgery, including the Norwood operation, even in the early stages of experience. Early clinical results are favorable but long-term follow-up and continued efforts are warranted to prove safety and reproducibility.

Selective sinus replacement for aortic root repair in bicuspid aortopathy.
To evaluate the results after selective sinus replacement (SSR) for aortic root remodeling in bicuspid aortopathy. ⋯ Patient-tailored root repair using SSR is a very effective and durable valve-sparing approach for bicuspid aortopathy. Aortic cusp repair is decisive for both abolishment of AI in bicuspid aortopathy and for the functional durability of the repaired aortic valve.
